Equine West Nile Encephalitis Prevention

Horses tend to become infected with West Nile Viral Encephalitis at a higher incidence than other domestic animals. The infection can be difficult to treat. As with most viral diseases, prevention through vaccination is preferable to treatment.

We recommend the following vaccination schedule.

Initial vaccination as soon as is practicable.

First booster vaccination three weeks following the initial immunization.

A second booster six months later.

A single yearly booster early each spring, prior to the most apparent mosquito season.

Ongoing experience may cause these recommendations to change. Please check back here or with our office often for updates.
